As I say I upload this code. The expire checking is that type: 1. If 15 days over it asked for key if key is not given it not run 2. If user change date & set it before installation date then it stop working. 3. If user set date before last using date then it also stop working. 4. If password is provided then no other checking will done so complexity is reduce. Hope you get all over idea after reading & testing this code. [you set a difficult for searching registry place for your app thats why no body will find it with out you how you keep registry value confidential it's your plus point ] In this example password is tanmay Thank you!
